CWS Asset Enhancement

CWS Asset Enhancement provides advanced technical expertise and in-depth analyses for internal and external clients to progress reservoir understanding and identify optimal completion methodologies. Asset Enhancement creates value for

stakeholders by applying multi-disciplinary knowledge of hydraulic fracture and reservoir factors which influence the planning phases, fracturing operations and post-frac

evaluations. We aim to be on the leading edge of market evaluation and innovative technology implementation to improve our client’s efficiencies and assist them in

making technically sound business decisions.

Equipment and Operations Sandstorm Proppant Delivery System

Technical Specifications Gravity Boxes can hold up to 1,200 tonnes of

sand as a set of six

45 foot enclosed endless belt delivering up to 10 tonnes of sand per minute

Incline conveyor capable of up to 20,000 pounds per minute straight to the blender

Computer remote control system housed by the Hydrabear

Hydrabear has enough hydraulic power to operate entire system and can be used to start the fracturing pumpers, eliminating the need for an additional tractor unit

Features & Benefits Larger sand volumes can be stored on-

site to decrease footprint by up to 30 percent

Significantly increases the rate of sand delivery while reducing highway transport equipment

Innovative gravity-feed system eliminates temperamental belts and conveyors

Self-contained scales improve accuracy of weight measurement

Enclosed conveyors and transition points ensure a silica dust controlled operation

The SandStorm proppant delivery system is a mobile, rapid-deployment proppant handling system that delivers

unmatched storage capacity, dust control and digital automation. Calfrac Well Services Photo
